Answer:

John incorrectly converted 40% instead of 4%.

Step-by-step explanation:

Given information is;

Price of car John wants to buy = £12,000

Expected increase = 4% = \frac{4}{100}

Expected increase = 0.04

Let,

Total amount after increase.

Total = (1+0.04) * Price of car

Total = 1.04 * £12,000

John incorrectly converted 40% instead of 4%.
